Isaiah 5:20 is a warning against moral confusion, the habit of renaming wrong as right and right as wrong. The prophet Isaiah pronounces “woe,” a solemn declaration of judgment, on people who blur the difference between good and evil. He speaks to the people of Judah and Jerusalem, and his words are aimed at a society that had lost its moral bearings while still keeping up its religious and political appearances.
Woe to those who call evil good, and good evil; who put darkness for light, and light for darkness; who put bitter for sweet, and sweet for bitter!

What Isaiah 5:20 Means
The verse begins with “woe,” which in the prophetic books works like a funeral cry, a sign that disaster is coming on those who are being described. The first phrase, “call evil good, and good evil,” describes people who change the labels attached to actions. Something harmful is dressed up as acceptable or admirable, and something decent is mocked, dismissed, or treated as embarrassing. The next two pairs, darkness and light, bitter and sweet, use images from everyday life to make the same point: people mistake what is harmful for what is helpful, and what is life-giving for what is harmful.
The verse does not promise that every mistaken judgment is a deliberate lie, nor does it say that Christians can never disagree about hard moral questions. What it condemns is a settled pattern of reversing what God has made clear, and a self-satisfied confidence that the reversal is wise. It is a diagnosis as much as a warning, and it asks the reader to notice whether their own standards have been quietly bent.
The Context of Isaiah 5:20
Isaiah 5 belongs to the first major section of the book, where the prophet confronts the covenant people with their injustice and idolatry. The chapter opens with the parable of the vineyard, which God planted and tended but which yielded wild grapes instead of good fruit. The woes in verses 8 through 23 spell out the specific failures: greed for land, drunken pleasure, contempt for God’s work, and the perversion of justice. Traditionally Isaiah, son of Amoz, is credited with the prophecy, and it was addressed to the people of Judah in the eighth century BC.
The surrounding verses matter a great deal. Verse 18 speaks of sin dragged along by cords of falsehood, and verse 19 records people daring God to hurry up and show what he will do. Verse 21 turns to those who are wise in their own eyes, and verse 23 names judges who acquit the guilty for a bribe. Read in that setting, the confusion of good and evil is not an abstract philosophical puzzle. It is the moral fog that lets powerful people excuse their own sin and punish the innocent.

A Short Prayer From Isaiah 5:20
Lord, you are the one who truly knows what is good and what is evil. I confess that I have sometimes called things right because they were convenient, comfortable, or popular, even when your word said otherwise. Open my eyes to see the darkness I have mistaken for light and the bitterness I have mistaken for sweetness. Give me a clear conscience and a willing heart to name the truth, even when it costs me something. Keep me humble, so that I never trust my own wisdom more than your word. Amen.
